請求大大指點迷津：
我從某範例中學到了加入 socialiteproviders/QQ的方法，但我需要的是Line，經如QQ方法泡製後得到結論如下：

於是網路爬文以及@firecold 大大的提醒找到了說明文:https://socialiteproviders.netlify.com/providers/line.html
經按照說明文指示設置步驟如下:

1

composer require socialiteproviders/line

2 修改app/Providers/EventServiceProvider

...
class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        Registered::class => [
            SendEmailVerificationNotification::class,
        ],
        'SocialiteProviders\Manager\SocialiteWasCalled' => [
            'SocialiteProviders\QQ\QqExtendSocialite@handle',
        ],

        \SocialiteProviders\Manager\SocialiteWasCalled::class => [
            // add your listeners (aka providers) here
            'SocialiteProviders\\Line\\LineExtendSocialite@handle',
        ],
    ];
...

3 .env中增加Line Developer 登录的key和秘钥

Line_KEY=164*****708
Line_SECRET=790f651*******ffb****80
Line_REDIRECT_URI=http://localhost:8000/auth/Line/callback

4 修改 config/services.php

....
'Line' => [
        'client_id' => env('Line_KEY'),
        'client_secret' => env('Line_SECRET'),
        'redirect' => env('Line_REDIRECT_URI'),
    ],
....

5 php artisan make:controller Auth/SocialitesLineController

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Socialite;

class SocialitesLineController extends Controller
{
    //跳转到Line授权页面
    public function line()
    {
        return Socialite::with('line')->redirect();
    }

    //用户授权后，跳转回来
    public function callback()
    {
        $info = Socialite::driver('line')->user();
        dump($info);
    }
}

6 配置路由

Route::namespace('Auth')->prefix('auth/line')->group(function () {
    Route::get('/', 'SocialitesLineController@line');
    Route::get('callback', 'SocialitesLineController@callback');
});

7 不知道哪裡錯了?點按連結後一直出現 "400 Bad Request"

求解！希望有大大指點，謝謝！
